ok mate Thanks for the reply. Julian.

Thanks!!!!!!!!!!!!

Hi Guys. As Rich mentioned I built the controler for this project. I went to Maplins and got one of their pre-built PWM controlers and a box. I already had the switches in stock but they could have also been bought at Maplins. Power supply was one that Rich bought from Ebay. As the motor is...

Hi, I am travelling to NYC at the end of October for a week on a family holiday. Do any of you guys who live there have a model engineering club or similar with a meeting any evening 24th to 28th october 2011. If so maybe I could come as a guest and meet a few of you. Regards Julian

Hi All, I am just about to build several boilers and need sight glasses for the water level. Rather than the glass tube sort I am looking at the glass plate type. I plan to use my cnc mill to make the mountings for them to sandwich the glass on the boiler. My question is what glass can I use...

Go to Wilko's or similar and buy a 99p wire brush. Screw it to a peice of wood to give the double handles. Julian

Definitely go for thermilites as they are dead cheap. About 75pence each from Wicks. Cut them with a wood saw and stack them how you need for the item you are soldering. Store them in a pile when not in use. Find an old steel or cast bbq for a stand. I've got a large steel plate on my bench for...

Excellent model....the best I've seen for a long time. It's better in person than on the pics and videos. They do not do it justice. Keep going mate. there's plenty to do.....the driven water pump, the generator, any other spinney twirly bits that can look good and enhance it!!!! julian

Who needs maths. I use a ruler and a pen or scribe. Two lines that cross at the pivot and meet the crank pin when set at 4 and 8 o'clock works for me. No offence student123 but the old saying of "measure twice cut once" is worth remembering. Through many cock-ups I have learnt this the hard...

Yes flywheel has not located properly. Just needs adjustment but will be coming off to paint model anyway. Need to make some levers to move the controls. Julian

As the household controler has been busy I have been able to rebuild the control and now have a better design. The principle is two brass rods machined to take several O rings to seal and narrow sections to connect different ports as they are moved. The bottom one directs air to one input on the...

First was avi second was mp4 from my blackberry. The control valve featured is undergoing a rebuild so once this is done and i am off which will be next thursday I will post new vid probably on youtube as p-buck does not appear to be working for me at the moment. Julian.

Will try again another day. Back at work tomorrow for six days. Julian.

This should be a better video. If still crap I will go on youtube. Valve was guess work and just works ok. I am not happy with it and will redesign today. Engine itself runs well. Julian

It's a crap video so will record another tomorrow. Julian.

No Tel, Didn't forget just ran out of time and had not copied link so here it is:-

Hi All, I like building small engines from whatever metal I have knocking about. This engine is a single cylinder double acting horizontal engine. Not built from plans but virtually 'thrown' together. I forgot to take any pics in the process but have this video of it working on air. The...

Hi, My last flat bottom holes several weeks ago were drilled almost to depth with a normal drill. Depth was measured to the POINT of the drill. I then flattened the end of the drill on the grinder and drilled very slowly with cutting paste and squared the bottom of the hole. I find at slow...

Hi, Correction to the above post....The cylinder is 46mm long with a 10mm thick piston. This gives a capacity of 2cc each end at bdc. In Tubal Caines book he gives the steam port in relation to the position of the crank. This will give a size relative to the stroke but does not allow for the...
